RICHARD B. OSBOURNE, INGRAM BOROUGH, PENNSYLVANIA, ASSIGNOR TO PHILLIPS I i MINE AND MILL SUPPLY 00., or PITTSBURGH, PENNSYLVANIA, a CORPORATION OF".

PENNSYLVANIA.

To all whom it may concern:

. Be it known that I, RICHARD B. OsBoURNn, a'citizen of the United States, residing at Ingram borough, in the county of Allegheny and State of Pennsylvania, have invented certa n new and useful Improvements in Car-Stops, of which the following is a specification, reference being had therein to the accompanymg drawing. p

"This invention hasrelation to car stops 4 and has for its'ob-j'ect the provision of novel mechanism for operating the horns or stops of the same. I

In coal mining, quarrying, excavatingv and other industries loaded cars of coal, stone, clay, etc.. are made up intoftrips or trains and hauled tosome point to be weighed,

dumped, hoisted or subjected to some other operation which requires them to pass a given point one at a time. These cars usually stand on a grade which will permit themto pass this point by gravity. To control the trips so that they will pass the given pointonly as desirecLa movable stop or check is placed-in the track on which the cars run which allows only the required'number of cars to pass it accordingly as the operator desires and'determines.

Heretoforethe horns or stops in mechanism of this character usually have been operated by means of a hand lever, but, with a trip of l aded cars standing against them it was difficult to move the hornsor stops, their operation by means of a hand lever involved severe'phvsical labor.

In the present invention the horns or stops 1 are operated by the weight of'a moving car acting through atrack treadle arranged in .the line of track so as to be depressed by the wheels of the car and certain mechanism connected with thistreadle and the horns or stops and operated by the movement of the treadle whereby, as the horns or stops are operated by the treadle, a strong s ring, connected withthe said connecting mechanism, is put under tension and the horns or stops locked in the position to which they have been brought by the movement of the treadle.

Provision is made for unlocking the born or stop operating mechanism and opening the. horns .or. stops by. the. pull. of the said.

spring. comprising a foot treadle and a tripper. the latter being arranged to bear against and move a pair of toggle arms or levers which constitute the locking means, and thus pass the next car through to the point where it is to be weighed, dumped, hoisted or otherwise manipulated.

'In the accompanying drawing which illustrates the invention; I

Figure 1 is a plan view of a car stop structure provided with my improvements, a portion of the main platform being broken away to show the mechanism beneath. v

Fig. 2, is a side elevation of the same.

Fig. 3. is a vertical sectional view on a larger scale, on the line w00 of Fig. 1.

Fig. 4'is-a side elevation of a modified form of my improvement, on the same scale as Fig. 3.

Fig. 5' is a-plan view of the construction shown in Fig. 4.

Figs. 6 and 7 are planand side views respectively and on a still larger scale of parts of the locking mechanism employed in the several forms of my improvement.

Figs. 8 and 9 are plan and side views respectively of another part of the locking mechanism, on the same scale as Figs. 6 and 7.

The apparatus con tituting my improvement is designed to be arranged in a line of track leading from a source of supply such as a mine, quarry or the like and is mounted on the ground or at any required elevation on suitable supports in the usual manner.-

The horn or stop mechanism is mounted on a platform or base plate 1, which is in turn mounted on L shaped beams, 2. 3 and at a suitable distance be ond the platform 1, there is a second platform 4. both platforms 1, and 4:, being supported on I beams 5 and 6.

The platform 1. carries two tracks designated respectively 7 and each of these tracks being composed of two L-shaped beams securely bolted together and to the platform 1. the tracks so formed being of approximately 2 shape as shown in cross section in Fig. 3.

p The platform 4 is provided with two tracks 9 and 10, alined with .the tracks 7 and 8, of platform 1, and inclined track sections 11 and 12, connect the track sections 7 and 8,1V1tl'ltll6 track sections 9 and 10.

Upon the outer side of each of the track sections 7 and 8 of platform 1, are arranged two longitudinally movable and oscillatory bolts 11 and 12, these bolts being mounted in bearing blocks 15, and provided with buffer springs 16.

The bolts 11, 12, carry horns or stops designated respectively 17, 18, the horns or stops being fast on the bolts and'the latter being so connected to the hereinafter described operating mechanism that the horns or stops can be turned to a. vertical or closed position, so as to stop a car on the tracks 7, 8, or to an outwardly inclined or open position, so as to allow a car to pass.

Below the platform 1, is arranged a cruciform lever having four arms, 21, 22, 23, and 24, this lever being fulcrumed on a vertical bolt 25. and mounted on a bracket 26 which is attached to the lower surface of platform 1. a

A rod 27 is pivotally attached to the arm 21, and extends to and beneath platform 4, and is there pivotally attached to an arm '28, depending from a track treadle 29 that is arranged in a cut out portion 30, of the track 9, and mounted on arms 31, 31, that are pivotally attached at their upper ends to the track treadle 29 and similarlyattached at their lower ends to brackets 32, 32,1depending from the platform 4.

r A strong spring 33, is attachd at one end to the arm 23 of the cruciform lever and at the other end is attached to the frame of platform 1, this spring being put under ten sion by the depression of the track treadle and consequent rotary movement ofthe cruciform lever. Y

A rod 34, is pivotally attached at one end to a curved arm 35, that depends from'bolt 11, and at its other end is pivotally attached to the arm 24 of the cru iform lever and a 7 similar rod 36, is pivotally attached at one end to a curved arm 37 that depends from bolt 12, and at its other end is pivotally attached to the arm 22, of the cruciform lever.

A link 38, composed of two parallel bars, is pivotally attached to the arm 24, of the V cruciform lever and atits-other end is pivthe cruciform lever by the pull of spring 33 is prevented, further movement to the right beyond the dotted line position Fig. 5, being stopped by contact of link bolt 39 with a tripper 41.

The function of the tripper 41, is to throw the toggle-lever lock off the substantially dead center position shown in dotted lines in Fig. 5, to a position where the pull of spring 33, can bring it to the full line position as shown in Figs. land 5. V

In order to assist the link 38 and link bolt 39 to assume the dotted line or locked position, a link 42 is pivotally attachedto the link bolt 39 at about the middle of the latter and the link 42, is forked at its outer end and embraces an angularly disposed and upwardly extending arm 43, carried by a connected by a crank rod 51, with a crank 1 arm 52, carried on the inner end of a rock shaft} 53, that is mounted in hangers 54,

depending from the platform'l.

The outer end of the rockshaft 53, carries a crank arm 55, that is connected to rod 56, extending under and to, near the extreme end of platform 4, where it is connected to a bell-crank lever 57, mounted on a hanger 5.8. The horizontal arm of the bell crank lever 57, is pivotally attached to the lower end of avertically movable foot treadle 59 and by the depression of this foot treadle, through the operation of the above described connecting parts, the tripper 41, is operated to -move and unlock the toggle-joint lock comprising link 38 and link-bolt 39, by moving them from the dotted line position shown in Fig. 5, to an equivalent position at the opposite side of a line intersecting the pivotal points of the toggle joint, whereupon the pull of the spring 33, exerted through the cruciform lever, will throw the link 38 and link bolt 39 into the full line position shown in Figs. 1 and 5.

- The description of the construction, arrangement and operation of parts hereinbefore described is equally applicable to all the figures of the drawing and consequently the same numerals have been employed to designate corresponding partsin the several figures, the only difference between the construction shown in Figs. 1, 2 and 3, and that shown in Figs. 4 and 5, being that in the con struction shown in Figs. 1, 2 and 3, two cruciform levers and two pairs of horns o1 stops,'are employed, while in the construction shown in ,Figs; 4v and 5-, but one cruciform lever and one pair of horns or stops are employed, the-locking means and other appurtenant parts being identically the same in both constructions. For this reason it has been unnecessary to show the platform 4, and the parts carried thereby in Figs. 4 and 5 and these parts have accordingly been omitted? Referring nowparticularly' to Figs' 1, 2'

and 3, it wil-l' be observed that a second cruciform leveris arranged below platform 1, this lever having four arms, 21', 22", 23, and 24, the arm 21, being connected to the arm 21 of the first described cruciform lever by connecting rods 19, 19, which are adjustably connected together by a turnbuckle 20, and this second "cruciform is pivotally mounted at 25, ona bracket 26, carried by platform 1.

The arm 21, f the second cruciform lever is pivot-ally connected to a rod 34' that is'pivotally attached to" a curved arm 35, that depends from the bolt 11, that carries the horn or stop 17', and the arm 24" of this cruciform leveris pivotally connected to arod 36 .that is attached at its outer end to a curved arm 37 that depends from the bolt 12 which carries the horn or stop 18.

It will be observed that the connection between the two cruciform levers and their respective horns or stops issuch that when the horns or stops 17 and 18 are in an outwardly extending or open position, the horns or stops 17, and 18, will be in a vertical or closed position and vice versa.

A. strong spiral spring 33, is attached at one end to the arm 23', and at the other end to the platform frame, and serves to draw the horns or stops 17, 18', into vertical or closed position when the toggle joint locking mechanism connected with arm 24 of the first described cruciform lever is released or unlocked by the tripper 41.

Opera-Zion.

Referring first to the construction shown in Figs. 1, 2, and 3, wherein two pairs of horns or stops are employed, and assuming that the direction of movement of the car or cars is in the direction indicated by the arrow X, and that the horns 1718 are opened and the horns 17', 18', are closed and that there is a single car at a position between the two pairs of horns and a trip or plurality of cars held back of the first named car by the horns 01' stops 17, 18'.

Jnder the action of gravity the car between the two pairs of horns 17, 18, and 17 181, will move in the direction indicated by arrow X, and pass onto and over the track treadle 2 As the car passes over the track treadle, depressing it, the horns 17, 18, will be closed and the horns 17', 18, will be opened, allowing the trip to advance to the horns or stops, 17, 18. During this operaby bell crank lever'57, and rod 56, rock sliaft53, and rod 51,-caus'es the tripper to press against the link bolt 39, and throw the toggle lock out of-lockedposition and allow the springs 33, 33 to open the front horns 17, 18, and thus allow another car to pass on, and close the-horns or stops 17, 18, thus holding back the trip or train until it is desired to send another car forward in the direction in'dicatedby arrow X. In the construction illustrated in Figs. 4 and 5, where'but one pair of horns or stops is employed, the operation is as follows.

Assuming that a car has passed the horns or stops, 17,18, moving in the direction indicated by 'the'arrovvX, the car will run onto the track treadle (it being understood that the apparatus shown in Figs. 4 and 5, is provided with the same operating ap purtenances as are shown in Figs. 1, 2, and

3,) and will depress the track treadle and closed horns or stops which will have as" sumed the closed or vertical position before the trip reaches them. To pass the next car along, the operator depresses the foot treadle 59, (see Figs, 1 and 2,) tripping the toggle joint lock, 58, 59. thus permitting spring 33, which was brought under tension by the depression of the track treadle, to open the horns and allow the car to pass, and this operation being repeated as long as there are any cars in the trip or train.

I claim:

1. In apparatus of the character described, the combination of a platform, tracks carried by the platform, horns or stops arranged adjacent to the platform tracks and adapted to be opened and closed, a track treadle arranged in a continuation of said platform tracks, mechanism connecting said horns or stops and said track treadle and 2.
